I always use names from mythologies. Minos, Atreus, Nestor, Thesus etc. but when I played sisterly lust I changed all the family names to Mario, Wario, Luigi and Waluigi
If you don't mind RPGM there's two games called Incest Story and Incest Story 2
Nano-Control was pretty good
For VNs, My Sister My Roommate is a decent one that I haven't seen mentioned yet
The Visit is complete but it's story is average
Lust Theory is pretty great (haven't played the final...
Dude is named Jobeo and I glanced through one of his games. Not only is the story the most boring thing to ever exist it's also the most exaggerated raceplay stuff you can find like borderline parody
It's HTML and not member+ but there's a game called gaia and adam (or adam and gaia idk) where your express purpose is to fuck girls who have daughters then you impregnate those daughters and so on
Not only is the walk thru mod there but most of the choices are really easy ones too like tell your sister she looks amazing or say nothing gee I wonder which one leads to sex
